Patented Aug. 25, 1936 UNITED STATES PATENT OFFICE Claims.

This invention relates to trusses and particularly the circumscribing member thereof and the construction and character of truss pad which is uniquelyand novelly associated with said member-to the end that a more emcient, effective and more comfortable .appliance is provided and one of the important objects is the provision of structural embodiments of the improvements in the aforementioned parts of the truss.

Another aim of the instant invention is the provision of a novel truss pad mounting which permits the pad of the truss to be adjusted and held at .a desired angle as the various angles become desirable or necessary, such adjustment being made by the wearer without the use of special equipment, tools, or the like.

Many minor objects of the invention will appear during the course of the following specification, referring to the accompanying drawing, wherein:

Figure 1 is a plan view of a truss made to embody the present invention.

Fig. 2 is a vertical, central, cross sectional view through one of the pads of the truss.

Fig. 3 is a section taken on line IIIIII of Fig. 2, and,

Fig. 4 is a fragmentary, side elevation of a portion of the truss, showing the resilient link in the circumscribing member thereof.

In constructing a truss embodying the present invention, a circumscribing member 6 is provided that comprises a plurality of arcuate, substantially rigid sections 8 and Hi.

The proximal ends of sections 8 and I0 are hingedly interconnected as at l2 and the free ends of sections I0 are provided with latch means l4 and I6 for the purpose of releasably securing the said ends together. Sections 8 have their proximal ends inclined outwardly to form an angled length l8 and these ends are joined together by a resilient link 20 which, when normal, is straight from end to end. This link 20 is riveted or otherwise rigidly secured to lengths l8 as at 22 and when the free ends of sections H] are secured together, link 20 is longitudinally arched and held under tension.

This construction in the circumscribing member 6 not only tends to swing the sections of member 6 to the open position when members |4I6 are released, but further tends to relieve the pressure upon the body of the wearer which would normally be exerted by sections 8 and I0. Obviously, as is well known in this art, the various sections of member 6 may be covered w th leather or the like as indicated by the illustrated embodiment of the invention in Fig. 1.

The unique truss pad which is combined with the aforementioned member 6v is of a desirable character in that it may be secured in any one of -a large number of angled positions and this pad comprises a plate 24, which has an inturned annular flange 26 for the purpose of gripping a resilient pad 28. Pad 28 has a cavity 30 formed in one side thereof for the hereinafter mentioned purpose and plate 24 has a slot 32 formed therein, which extends from the axis of plate 24 radially toward the edge thereof.

A threaded bolt 34 extends through slot 32 and an aperture 36 formed in section 8 and is engaged by a threaded nut 38 which may be manually manipulated by the wearer when it is desired to adjust the truss pad. Opposed washers 40 and 42 loosely threaded upon bolt 34 lie on either side of plate 24 and the head 44 of bolt 34 is of the type illustrated in Fig. 2.

A pair of dome-shaped members 46 and 48 are interposed between washer 42 and member 8 and these dome-shaped members have their axes on the longitudinal axis of bolt 34 so that as members 4B and 48 slide over each other to dispose pad 28 at an angle, nut 33 might be tightened after reaching the adjusted position to draw together the abutting surfaces of members 45 and 48 and create a tight frictional interlocking of said members. The entire pad structure will thereby be held against accidental displacement. These dome-shaped members 48 and 48 have openings .and the opening in the innermost member 48 is appreciably larger than the opening 5 formed through member 46. Bolt 34 passes through these openings 50 and 52 in members 46 and 48 respectively and as member 46 moves over the outer surface of member 48, clearance is provided for bolt 34.

From the foregoing it will be observed that the pad itself is not only adjustably movable through the sliding of bolt 34 in slot 32, but is simultaneously positionable at desirable angles to the plane of member 8 at the zone of connection.

In the type of truss illustrated, two pads are employed, one on each side of resilient link 20 and either one may serve to support the rupture, while the other may act as a stabilizing means for the rest of the truss.

The operation, advantages and novel features of a truss embodying this invention have been made clear during the course of the foregoing specification, and while one form of embodiment has been illustrated and described, it is desired 55 to be limited only by the spirit of the invention and scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A truss of the character described comprising a plurality of interconnected sections forming a circumscribing member having ends detachably secured together; and a pad carried by at least one of said sections, one of said sections being resilient, the remaining sections being rigid, said resilient section being in opposed relation to the said ends when the latter are secured together and longitudinally arched by tension created therein when the sections are secured together.

2. A truss of the character described comprising a plurality of arcuate, substantially rigid sections; means for interconnecting said sections; and a pad on at least one of said sections, the proximal ends of two adjoining sections being inclined outwardly, the means for interconnecting said two sections being a normally straight resilient link connected to the outwardly inclined ends, longitudinally arched under tension.

3. A truss of the character described comprising a plurality of substantially rigid sections; means for interconnecting said sections; and a pad carried by each of two of said sections, the proximal ends of said two pad-carrying sections being inclined outwardly, the means for interconnecting said two sections being a normally straight resilient link connected to the outwardly inclined ends and longitudinally arched under tension.

4. A truss of the character described comprising two sets of arcuate, rigid sections; pads carried by certain of said sections; means for detachably securing together each of said sets at their one end; and a resilient link permanently joining together said sets at the other end thereof, said sections of each set having an outwardly inclined length at the last mentioned ends of the sets, said resilient link being normally straight and connected to the outwardly inclined lengths of the sections of each set whereby it is arched and held under tension when the detachable securing means is operating to hold together the ends of said sets.

- 5. A truss of the character described comprising 1 two sets of arcuate, rigid sections; pads carried by certain of said sections; means for detachably securing together each of said sets at their one end; and a resilient link permanently joining together said sets at the other end thereof, said sections of each set having an outwardly inclined length at the last mentioned ends of the sets, said resilient link being normally straight and connected to the outwardly inclined lengths of the sections of each set whereby it is arched and 25 held under tension when the detachable securing means is operating to hold together the ends of said sets, the sections of each set respectively being hingedly interconnected to co-operate with said resilient link in moving the parts of the truss 30 to the open position.
